In making the legal case against Obamacare’s individual mandate, challengers have argued that the framers of our Constitution would certainly have found such a measure to be unconstitutional. Nevermind that nothing in the text or history of the Constitution’s Commerce Clause indicates that Congress cannot mandate commercial purchases. The framers, challengers have claimed, thought a constitutional ban on purchase mandates was too “obvious” to mention. Their core basis for this claim is that purchase mandates are unprecedented, which they say would not be the case if it was understood this power existed.
